Removing the Acrylic Enclosure
This step applies only to users who purchased the acrylic enclosure. If not purchased, skip this step!
Use a screwdriver to remove the screws securing the acrylic panels, then remove the mounting pillars and acrylic panels.
Removing the Heatsink (8420B)
Before assembling the AI PC Developer Kit, the Radxa 8420B heatsink must be removed
Step 1: Disconnect the Heatsink Cable
Disconnect the heatsink cable from the Orion O6 motherboard.
Step 2: Remove the Heatsink
Loosen the four heatsink screws in a cross pattern using a screwdriver to ensure even force distribution.
Assembling the AI PC Developer Kit
Step 1: Apply Thermal Paste
Apply an appropriate amount of thermal paste onto the motherboard's SOC chip.
Step 2: Secure the Heatsink
Align the heatsink's mounting pillars with the motherboard's mounting holes. Tighten the four spring screws in a cross pattern to avoid damaging the chip. After securing the heatsink, connect the fan cable to the corresponding motherboard header.
Step 3: Install the Button
Insert the power button into the designated hole on the enclosure.
Step 4: Install the LED Panel
Confirm the LED board orientation based on its onboard LED position before installation
Install the LED board onto the corresponding motherboard header.
Step 5: Secure the Motherboard
Insert the motherboard into the enclosure at an angle, ensuring all ports align with the enclosure's cutouts. Secure the motherboard with four CM2.5*5mm screws.
Step 6 (optional): Install PCIe to OCuLink adapter board
Primarily used for external GPU expansion. Install as needed.
Installation Instructions:
1.Remove the protective tape from the adapter's gold fingers (contact area between adapter and slot).
2.Align the adapter's external interface side with the enclosure's cutout (Diagram ①).
3.Align the adapter's slot with the motherboard's slot (Diagram ②), then gently press down (Diagram ③). The slot latch will automatically engage when properly installed.
Step 7 (Optional): Install PCIe to M.2 Adapter Board
Primarily used for expanding M.2 SSD storage. Install as needed.
The SSD shown in the diagram must be purchased separately. Use a CM2*4mm screw to secure the SSD
Installation Instructions:
1.Remove the protective tape from the adapter's gold fingers.
2.Align the adapter's slot with the motherboard's slot and gently press down (refer to PCIe to OCuLink adapter installation diagram). Note: The PCIe to M.2 adapter doesn't require alignment with enclosure cutouts.
Step 8: Install the Enclosure Bracket
Orient the bracket with its notch facing the enclosure's ports. Align the bracket's screw holes with the enclosure's mounting points, then secure with seven KM2*6mm screws.
Step 9: Install the Silicone Plug
For users not installing PCIe adapters or only installing the PCIe to M.2 adapter, use the silicone plug to cover unused ports and prevent dust ingress.
Step 10: Install Ventilation Baffles
Early adopters will receive two ventilation baffles (one spare). Later versions will come with pre-installed baffles, making this step unnecessary
Attach the ventilation baffle to the base's exhaust vents to direct all airflow through the bottom cover.
Step 11: Install the Bottom Cover
Align the bottom cover's ventilation holes with the enclosure's ports, then secure with CM3*8mm screws.
Step 12: Install the Rubber Feet
Attach the four rubber feet to the designated positions on the bottom cover.
